Warfarin Sodium and forgetfulness

Kind of funny I forgot one of my main complaints of this drug, but it is the forgetfulness. My mind is not as sharp as it used to be, sometimes I feel like I am in a fog. My recall can be really bad, too. Someone can ask me a simple question and I draw a blank. My dad was on this stuff for years, he has since passed, but he had the same memory problems, although no one ever thought it was from Warfarin, but now I wonder.

I, too have been losing my hair. I always said to myself, "I may not have much going for me but I do have good hair and good teeth." Now my scalp is showing, and I'm pretty bummed out about it. I'm also having nausea during the morning hours, and then headaches that wake me up from my sleep.

I have been on Coumadin for about 2 months now after surviving a cerebral sinus venous thrombosis (blood clot on my brain - akin to a stroke). I am s 34 yo female who races triathlons and leads a very active healthy lifestyle. My side effects seem to be mild compared to what I read of others. I am on 5mg/day, except 1 day a week I take 10mg. My INR has been pretty stable. The side effects I notice are mild forgetfulness which I am hoping goes away as I start my 3rd year of law school next week! I also had some weird skin peeling on my hands, but that has subsided. I seem to urinate more often than normal and soda pop tastes weird to me now. Anyone else experience the frequent urination and/or taste issues?
Thanks!

Symptoms which were not in existence prior to staring on warfarin although my doctors say they don't think it's warfarin I'm sure it is. I usually need to take around 9.5 to 10mg but my INR is never stable.
Side effects are extreme fatigue, fuzzy thinking, forgetfulness, hot rosy cheeks.
